Read the detailed description

This is a Prospective pilot study that will be performed at the Fetal Care Unit at Ain Shams University Maternity Hospital.

Ninety pregnant women will be recruited from the the Fetal Care Unit who will fulfill the inclusion criteria. They will be counseled to be included into the study.

All cases will be subjected to:

  1. Full history taking including patient's age, parity, last menstrual period, estimated gestational age by dates, past history of medical disorders, clinical examinations (General and abdominal).
  2. Two-Dimensional Ultrasound and Five-Dimensional Ultrasound will be done for all cases for assessment of fetal femur length .

The FL at Two-Dimensional Ultrasound (Gold standard) will be made from the center of the 'U' shape at each end of the bone.

The FL at Five-Dimensional Ultrasound will be measured by Pressing Five-Dimensional Ultrasound long bone Button to extract Fetal Long Bones automatically.

The estimation of gestational age by femur length by Two-Dimensional Ultrasound and Five-Dimensional Ultrasound will be compared to gestational age calculated by accurate dates of the last menstrual period.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Gestational Age Calculated by Accurate Dates of the Last Menstrual Period

    The patient must be sure of her last normal menstrual period, last three regular cycles and no hormonal contraception before pregnancy.

    Gestational age calculated by the last menstrual period

    Measured: 26 - 40 weeks of gestation

Secondary outcomes (2)
  1. Gestational Age Calculated by Femur Length Measurement by Two-Dimensional Ultrasound

    The femur length at Two-Dimensional Ultrasound (Gold standard) was made from the center of the 'U' shape at each end of the bone. After the long axis of the fetus was identified, the transducer was turned 90 degrees to produce a cross sectional image of fetal trunk, maintaining the 90 degrees angle until the lower spine and iliac crest were identified, then the transducer was rotated until a full femur was imaged. The femur length was measured from the center of the "U" shape at each end of the bone; this represented the length of the metaphysis).

    then , Gestational Age Calculated by femur length measurement

    Measured: 26 - 40 weeks of gestation

  2. Gestational Age Calculated by Femur Length Measurement by Five-Dimensional Ultrasound

    The femur length at Five-Dimensional Ultrasound: To obtain 3D volume data, the entire bone length of the femur was identified on the screen, as in the 2D-ultrasound measurement, and the long axis of the femur was placed in the direction of the x axis in the image in which the ultrasound beam was perpendicular to the bone. The 5D LB set key was pressed on the system, wherein the system automatically analyzed the 3D volume data, reconstructed the 3D image of the long bones, and displayed the measured length of the femur length on the screen was measured by pressing 5D LB Button to extract Fetal Long Bones automatically.

    then, gestational Age Calculated by femur length measurement

    Measured: 26 - 40 weeks of gestation

Questions about this trial

What is this clinical trial studying?

An observational study of Automated Fetal Femur Length Measurement by Five-Dimensional Ultrasound, run by Ain Shams University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Aug 2016. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Aug 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Gestational Age Calculated by Accurate Dates of the Last Menstrual Period (time frame: 26 - 40 weeks of gestation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Aug 2016.
